LOS ANGELES – Scaffolding erected along the red carpet at the Shrine Auditorium for coverage of Sunday’s Academy Awards collapsed Thursday, injuring five people, one critically.

The scaffolding was the type commonly used to hold spotlights. The mangled structure fell onto the red carpet that will be used by celebrities as they enter the auditorium for the awards ceremony.

The scaffolding stood 20 feet and just gave way, said Fire Department spokesman Bob Collis. Division of Occupational Safety and Health inspectors were called and will determine what happened, he said.

One person was critically injured, one seriously, one had minor to serious injuries and two had minor injuries, Collis said.

They were taken to two area hospitals.
